TRACK test Corvette Z06 against Porsche 911 GT3 R-S
Result
"the test was one gro? ?erraschung f?mich. We have here two v?ig different sports car concepts, which can be moved erwartungsgem?auch v?ig differently. On the side with the Corvette Z06 a genuine Powercar from the USA with 7,0 litres capacity to the asking price. On the other side a racing car with Stra?nzulassung. To call the Porsche 911 GT3 R-S something else, w? missed. During the series tyre the two separate worlds likewise. Everyday life-suited Runflat tires on the V8-Monster, Semi Slicks on the finely balanced racer. And which happens? The two separate f at the end only? Tenth ofs a second. The Porsche makes exactly what you want. The Corvette dr?t as wildly forward. But you can convert the strength many more badly, because you must k?fen st?ig. You need in the Corvette also more courage than in the Porsche, it come even in the fourth course still crosswise. If you this strength on the bitumen bring k?test. Semi Slicks does not give it f?die Z06 to time yet, then to w? it a genuine monster. The Porsche is that absolutely rounds and snaps total package."
